Abstract
The invention relates to a cordyceps extract and a preparation method thereof for a preparation, and belongs to the technical field of the extraction and the application of active components from a Chinese traditional medicine. The ultrasonic processing and the extraction method of combining alcohol extraction and water extraction are utilized. The extraction rate of the active components of polysaccharide can be increased by the ultrasonic processing, and since the alcohol extraction and the water extraction are combined, not only the extraction rate of the active components of the polysaccharide can be increased, but also the solvent is saved, the biological activity of the cordyceps polysaccharide is ensured, the utilization ratio of the raw material is increased to the utmost extent, the production cost is reduced, and the invention is suitable for the large-scale industrial production.
Description
Technical field:
The present invention relates to the preparation method of a kind of Cordyceps extract and preparation thereof, belong to Chinese medicine extracts active ingredients and applied technical field, also belong to field of traditional Chinese medicine pharmacy.
Background technology:
Cordyceps (Cordyceps militaris), another name Cordyceps militaris (L.) Link., Cordyceps militaris.Cordyceps militaris (L.) Link. belongs to Ascomycotina (Ascomycotina), Clavicipitaceae (Clavicipitaceae), Cordyceps (Cordyceps).Under the Cordyceps situation that supply falls short of demand, the Cordyceps militaris (L.) Link. equally celebrated for their achievements with Cordyceps is subjected to people's attention in the world day by day, and its exploitation and production have been developed new nutrient source and medicine source for body-care and field of medicaments." Xinhua's book on Chinese herbal medicine outline " record Cordyceps militaris (L.) Link. effects such as " property are flat, and sweet in the mouth has the lung benefiting kidney, mends marrow, hemostasis and phlegm " is used for diseases such as pulmonary tuberculosis, old man's weakness and anemia, is the Chinese crude drug of preciousness.Cordyceps militaris (L.) Link. has multiple pharmacological effect: can blood fat reducing, prevent arteriosclerosis, and the protection heart, cerebral tissue, tranquilizing soporific strengthens macrophage activity, anticancer, antiinflammatory, antibiotic, anti-hypoxia etc.; Cordyceps militaris (L.) Link. can be used for treating emphysema, prostate hyperplasia; Cordyceps militaris (L.) Link. can also human body immunity improving power, and auxiliary renal transplant recipients is got well, and increases sexual function etc.
The technology features of original capsule, tablet is to adopt the method for decocting in water precipitate with ethanol to extract multiple proteins and polysaccharide effective ingredient in the Cordyceps thalline Cordyceps thalline, and effective ingredient often extracts not exclusively.
Summary of the invention:
The object of the present invention is to provide a kind of Cordyceps extract, contain the effective active composition of Cordyceps.
The present invention also provides its preparation method, is applicable to suitability for industrialized production.
The present invention also provides the application of this Cordyceps extract in the preparation medicine, discloses corresponding drop pill, dispersible tablet and slow releasing tablet pharmaceutical dosage form.
Cordyceps extract of the present invention can obtain by the following method:
Get Cordyceps militaris (L.)
